Fix seat markup pricing - prioritize seat maps over offer services for total calculation

[Copilot]

When seat markup was applied using the markup prop, the component would display the correct marked-up price in the seat selection interface but would still calculate totals using the original (non-marked-up) prices from the offer's available_services.

The Problem

Consider this scenario:

• Original seat price: 23.39 EUR
• 10% markup applied: markup: { seats: { rate: 0.1, amount: 0 } }
• Expected total: 25.73 EUR (23.39 × 1.1)
• Actual total displayed: 23.39 EUR ❌

The issue was in the getTotalAmountForServices function which had this logic:

1. First check if service ID exists in offer's available_services (original prices)
2. If found, use that price and stop
3. Only if not found, check seat maps (marked-up prices)

Since seat services exist in both the offer AND seat maps, it would always use the original price from step 1.

The Solution

Modified getTotalAmountForServices to prioritize seat maps over offer services:

1. First check if service ID exists in seat maps (marked-up prices)
2. If found, use that price
3. Otherwise, fall back to offer's available_services (for non-seat services)

This ensures:

• ✅ Seat services use marked-up prices from seat maps
• ✅ Other services (baggage, etc.) continue working as before
• ✅ Backward compatibility maintained for cases without seat maps

Testing

Added comprehensive tests covering:

• Seat services with markup applied correctly
• Mixed services (seats + baggage) handled properly
• Fallback to offer services when not found in seat maps
• Backward compatibility when no seat maps provided

Fixes #416.

Fixed the linter errors. The issues were prettier formatting problems in both modified files. Applied automatic formatting fixes and all lint checks now pass. (f98da31)
